Hcg after miscarriage

Bethany
I had my miscarriage march 6th and two days before that my hcg levels we're only 2012. They're not following up with blood work until they hit 0 but I thought they be gone by now sense they wasn't high at all I was only a few weeks along. I'm just wondering for anyone else that had a miscarriage how long did it take until your levels were back down?
